NA110AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel for both rings and balls, combined with a brass cage, this bearing ensures high strength and durability. The Endura-kote chromium plating provides superior corrosion resistance, extending service life in harsh environments.
Optimized Load Capacity: With a radial dynamic load rating of 1072 lbf and axial static load rating of 2810 lbf, the NA110AR0 effectively handles combined loads while maintaining precision. The 30° contact angle provides optimal load distribution between radial and axial directions.
Precision Engineering: The ABEC-1 tolerance class ensures consistent dimensional accuracy, while the tight radial internal clearance (0.0000 – 0.0005") guarantees smooth operation and minimal vibration. The precise bearing dimensions (11" bore, 11.5" OD) facilitate easy integration into existing systems.
Temperature Stability: Operating range of -30°C to 110°C with pre-lubrication ensures reliable performance across various environmental conditions without maintenance requirements.
